Damn Reincarnation

Hamel, a warrior who traveled with his colleagues to exterminate the devil. Yet, he died just before the battle with the devil started.
“Yes.”
What the hell?
He was reborn as the descendant of his fellow warrior, Vermouth.
The descendant from the bloodline of the great Vermouth, Hamel. No, he was now Eugene Ryan Hart.
“It was already enough me having the delusion that I was a genius in my past life. But… this… It’s… It’s incomparable.’
From a dying body to a new body, he has the achievement that he did not have in his previous life.
And, a reincarnation of an unknown origin, the reality of living together with the demons.
Facing a new world where everything is questionable.
The journey of the unfinished previous life begins with Eugene’s body.
